  3. What a Reward! 5 Star Review

    Posted by on 2nd Jun 2016

    Very easy to install and what a difference in the amount of light with hardly any current draw from our RV batteries.

  4. Wish we had upgraded sooner to LED's 5 Star Review

    Posted by on 23rd May 2016

    We replaced all of our RV's flourescent tube lights with LED tube bulbs from M4 and are delighted with the results. That included 5, 18" T8 double flourescent tube fixtures, 4, 12" T5 double flourescent tube fixtures. The rewiring was soooo easy, thanks to M4's well writen instructions both online and those that come with the bulbs. Each fixture rewire took less than 10 minutes. We were so pleased with how these bulbs lit up our RV that we then ordered 11 non-flourescent bulbs so we could replace all of our bathroom vanity and ceiling bulbs. Oh what a difference the LED bulbs from M4 make. We had one question that we needed M4 to answer and we got our question promptly answered on a weekend day, even though M4 is closed on weekends. M4 is by far the best business I have ever dealt with online. Great Job M4!

  5. No.1 LED replacement fluorescent Tube 5 Star Review

    Posted by on 17th May 2016

    My RV has 5 18" double tube fluorescent light fixture in it.
    I have replaced all fixtures with M4 replacement LED tubes.
    Some electrical work was required, but over all was a snap.
    A GREAT product.

    Fluorescent light was interfering with electricity on motor home. Installed led lights. Wonderful! A/c stays on. It is a miracle!

  9. 18" Tube Lights 5 Star Review

    Posted by on 16th Dec 2015

    Two years ago, I ordered and installed four 18" CW Tubes, so easy, just hook ground to one end and power to oppsite (12V, cutting
    out old transformer control) They were so good, I ordered 8 more this fall. We read a lot, and under any two bulbs, it is like day light.
    They ceretianly will brighten your RV. Using so much less energy,
    when on 'house battries'. These bulbs fit into same sockets, with
    no wires hanging out. There is no way that M4, could improve their
    business, they are 'tops', and deliver! 'Merry CHRISTmas'

  10. What an improvement in RV lighting! 4 Star Review

    Posted by on 7th Dec 2015

    We ordeted replacement tubes for the main part of our coach to see how we liked them, 18" & 12". They arrived quickly & were packed really well. We liked them so well that we ordered replacements foe the rest of the coach. These LED tubes are such an improvement in the amount of light in our RV. Plus they really reduce the power drain when using the house batteries & not shore power. The instructions were easy to follow. The only reason I didn't give them 5 stars is the negative influence they have on TVs. This is explained in the information so we weighed this against the benefits & have learned to use non-tube LED lights when watching television.
